[CRIU] Dump Process

[Thouraya TH]

You use 3 terms interchangeably -- interrupt, stop and kill the process.
--Yes
i want just stay running the ./test.sh script

root at thouraya-Lenovo-3000-N500:/home/thouraya# criu dump -vvvv -o dump.log
*-R* -t 4172 --shell-job && echo OK
OK
it works :)

Please, i have two other questions which are importants for me:
1) i'd like to restart process on a new machine
Here is restore files in my current machine:
root at thouraya-Lenovo-3000-N500:/home/thouraya/imgDir# criu restore -d -vvv
-o restore.log && echo OK
OK
root at thouraya-Lenovo-3000-N500:/home/thouraya/imgDir# ls
cgroup.img         fifo-data.img        netlinksk.img      sigacts-20099.img

eventpoll-tfd.img  inetsk.img           pipes.img          stats-restore
ext-files.img      inotify.img          pstree.img         tty.img
fanotify.img       inotify-wd.img       reg-files.img      tty-info.img
fanotify-mark.img  inventory.img        remap-fpath.img    tunfile.img
fdinfo-2.img       mm-19654.img         restore.log        unixsk.img
fdinfo-3.img       mm-20099.img         sigacts-19654.img

Question: i ask what can i do to restart process on the new machine ? i
have just to send imgDir to the new machine and run the command criu
restore ?
i cant't test this now because i haven't another machine with criu ..

2) i have to test criu dumping process with an application ( a binary file
which uses some input files)
i have tested this with blcr, when i restart the process on a new machine,
i have to migrate input fileson the machine
is it the same with criu ?

Thanks a lot for help and answers.
Bests.
